Abstract

A proton therapy system based on a compact superconducting cyclotron, including: a superconducting cyclotron system, an energy selection system, a beam transport system, a fixed therapy room subsystem and a rotating frame therapy subsystem; a fixed-energy proton beam extracted from a superconducting cyclotron of the superconducting cyclotron system is adjusted into a continuous and adjustable proton beam of 70 MeV to 200 MeV by the energy selection system, thus realizing a longitudinal adjustment for a proton range during treating a tumor, and the continuous and adjustable proton beam is respectively transmitted to the fixed therapy room subsystem and the rotating frame therapy subsystem by the beam transport system. The cooperative control of the superconducting cyclotron system, the energy selection system, the beam transport system and the therapy head realizes the transverse expansion of proton beams, thus realizing intensity modulated radiation therapy for the tumor.

Description

technical field

[0001] The invention belongs to the field of medical equipment, in particular to a proton therapy system based on a compact superconducting cyclotron. Background technique

[0002] With the current rising demand for cancer treatment, proton therapy has become an effective means of treating tumors. Proton therapy has a unique "Bragg peak" biological effect, the dose loss on the way to the target area is very small, protons can release most of their energy at a predetermined depth in the body, forming a "Bragg peak" The precise energy release trajectory can precisely treat the tumor area and effectively kill the lesion. At the same time, the purpose of reducing the damage to surrounding healthy tissues is to greatly reduce the damage to normal cells, improve the comfort of patients during treatment, and improve the quality of life of patients after surgery. Compared with ordinary radiotherapy technology, proton therapy has a wide range of treatment, high cure...
